Any decently hot girl can just go find some random guy she thinks is good looking and ask him up to her room.

Hes never going to say no...

Hahaha.

But if you don't like to sleep around, have a guy who is just not there that minute (and don't want to cheat), or just want to get off quickly.....why waste your time with a random guy, who might not even know how to get you off, when you can just do it yourself?
